the King of; Great Britain, residing at 'Mendeberie, Somerton," in theState of New South 'Wales, Australia, and esiKem Street, Sydney, in-theState of Newbouth' have invent-c ed; cirtain-new and useful Improvementsin jects of Wales, Australia, respectively,

Churn-aotwhich' the following is a specifi at p 1 I V Briefly stated thepresent invention conthereceptaclecontaining the cream a continuousrevolving movement around a crank The invention further contemplates theprovision ofmeansv for imparting a tilting movement to the creamreceptacle simu ltaneously with the revolving motion mentioned In thepreferred form of churn accordin to this invention, thetwo motionsmentioned arecombined to secure the highest'degree of Pturbulence orsurging to the cream when the churn isvin' operation. v

that is during interval of each revolution of the crank the jar contentswill tend to move upward, sidewise and downward and to rock to and fro,which particular connbination of motions will constantly agitate and mixup the contents and so produce the butterin a remarkably short time. Themanipulation of the clips herembe-f fore: mentioned for securing thecap. upon the cream vessel is as follows: ThevesselE having been placedin position onfthe table Gv the wire clip- E, E is brought over for its.upper end to rest upon the cap E, at the same time allowing the link Eto he over to the left, then the clip E? E is brought over to permit ofits upper end to rest upon E, E-',.When both are pressed hard down ontothe cap and the link E turned over to attached cap theright and its ,endplaced under the hold fast E; which hold-fast E is capableof beingturned upon its screw E by which. it is kept in position upon the cap E.For the release of the cap the reverse of the afore described operationswill be carried out.

Figs. 4 and 5 illustrate a modification of the clip above described forsecuring the cap onto the cream vessel in which two vertical screw boltsP and P are secured intothe table G and are fitted at their threadedupper ends with winged nuts P and P for tightening the clamping plate Rwith its E onto the cream vessel.
